The Geothermal Process

From the Video: Digging a well of of 4-5 km. Then, cold water is injected a high pressure down the well to fracture the hard rock. Then more cold water is injected into the fractured rock. The water is then heated and brought back up through other pipes. This water then becomes steam that creates electricity by running a turbine. The cold water is then pumped back down into the geothermal reservoir, going through this process again in an endless progression.
